All three cameras worked fine, removed one due to building work and all stopped working. Orange livebox 5 5GHz and 2.4GHz as a router with optic cable. Cameras refused Livebox as it would not pickup 2.4 GHz allthough they worked before. Added Netgear WN2000rpt router on a seperate band at 2.4GHz and one camera loaded but app refused to recognise it saying it was 5GHz I have not tried all three. Flashing green light went to on all the time and camera reported that the connection was made successfully. I been trying for three days with no sucess what is wrong???
